What kind of engine oil does Beijing Hyundai use?

[MacAutumn]

Beijing Hyundai vehicles use API-SM/GF-4-SAE-5W-20 engine oil from Beijing Hyundai's original equipment manufacturer, which needs to be replaced every 5,000 kilometers. Fully synthetic engine oil can also be used, with 5W-30 or 40 being acceptable options. Information about engine oil is as follows: 1. The "0W-30" on the label of the engine oil packaging refers to the viscosity grade of the oil. The "W" stands for winter, and the smaller the number before it, the better the low-temperature fluidity of the oil, the lower the environmental temperature it can be used in, and the better its ability to protect the engine during cold starts. 2. Engine oil, motor oil, or engine lubricant is a substance enhanced with additives in base oil, mainly containing anti-wear additives, detergents, dispersants, and multi-grade oil viscosity index improvers. Engine oil is used for lubricating internal combustion engines. The main functions of engine oil are to reduce friction and wear on moving parts and to remove sludge (one of the functions of dispersants) and varnish (cleaners) from the engine.
